Clustering-Based Energy-Efficient Broadcast Tree in Wireless Networks

An Energy Efficient Clustering Method using Bat Algorithm and Mobile Sink in Wireless Sensor Networks

Wireless sensor networks (WSNs) consist of sensor nodes with limited energy. Energy efficiency is an important issue in WSNs as the sensor nodes are deployed in rugged and non-care areas and consume a lot of energy to send data to the central station or sink if they want to communicate directly with the sink. Recently, the IEEE 802.15.4 protocol is employed as a low-power, low-cost, and low rat...

Hybrid Bio-Inspired Clustering Algorithm for Energy Efficient Wireless Sensor Networks

In order to achieve the sensing, communication and processing tasks of Wireless Sensor Networks, an energy-efficient routing protocol is required to manage the dissipated energy of the network and to minimalize the traffic and the overhead during the data transmission stages. Clustering is the most common technique to balance energy consumption amongst all sensor nodes throughout the network. I...

Random Tree Optimization for Energy-Efficient Broadcast in All-Wireless Networks

We study optimization methods for source-initiated energy-efficient broadcast in all-wireless networks. Past studies on energy-efficient broadcast [1,3,5] focus on deterministic optimization to construct an energy-efficient broadcast tree. We present a Random Tree Optimization (RTO) approach that transforms the deterministic optimization problem into a related stochastic one. We apply the cross...

Probabilistic Optimization for Energy-Efficient Broadcast in All-Wireless Networks

We study optimization methods for source-initiated energyefficient broadcast in all-wireless networks. The minimum energy broadcast (MEB) problem in wireless networks proved to be NP-complete [1,4]. Past studies on MEB problem [1,2,5,8,9] focus on deterministic optimization to construct energy-efficient broadcast tree. In this paper, we present a probabilistic optimization approach, the Randomi...
